SKIN BARRIER FUNCTION: LOOK AFTER YOUR SKIN SO IT CAN LOOK AFTER YOU
While skincare companies are touting ‘hydration’, ‘anti-ageing’ and a ‘glowing complexion’ as reasons to care for your skin, at Biologi, those things are all bonuses rather than the primary objective.
Of course, we all want beautiful, glowing skin that improves confidence and makes us feel as good as we look.
But, for us, the most important reason to use good quality, natural skincare filled with nourishing actives is to repair, protect and nurture the skin’s barrier function.
What is the skin barrier function?
The top layer of skin is the ‘stratum corneum’ and not even a fraction of a millimetre thick.
It’s made up of dead skin cells, fatty acids, cholesterol, lipids and ceramides which hold skin cells together.
This external layer has an important role to play and forms the protective barrier to the body’s largest organ.
Primary functions of the skin barrier:
- Improve hydration by keeping natural moisture locked in skin cells
- Protect the body from external toxins such as pollution, bacteria and harmful UV rays.
The body is designed to repair itself, and when skin cells don’t receive the active nutrients they need for performance, the barrier function becomes damaged. This can display in any or all of the following symptoms on your skin:
- Bumps under the skin
- Breakouts and acne
Whatever your symptoms, the result is the same; your protective dermal layer is damaged impacting the barrier function, and this could be harming your health.
Problems caused by a damaged barrier function
Often, we look at sensitised skin as a bit of an inconvenience or turn to skincare products to try and cure it, but there’s a bigger picture.
You may have noticed the signs that your skin’s protective layer is damaged, but what does this mean for your body?
Whatever the signs and symptoms, sensitised skin means the barrier function is weak and failing to work efficiently to keep toxins out and moisture in.
Toxins and allergens found in the environment which the barrier function protects against, are then penetrating the deeper layers of the skin causing irritation on a cellular level.
With a weakened barrier function, environmental toxins (such as those found in pollution) can even enter your system.
A weak barrier function also increases the risk of long-term chronic skin conditions such as dermatitis, psoriasis and eczema.
When the barrier function is damaged, toxins may be stored in your skin rather than removed. Your skin can react to those toxins by becoming inflamed which presents itself in redness, acne, breakouts and eventually, more severe skin conditions such as dermatitis, psoriasis, and eczema.
If the oily lipids in the dermal barrier stop functioning, the skin’s natural moisturising process is disturbed. Not only will you end up with dry skin, but this can also lead to cracking, sores, and discomfort which, in many cases, is completely avoidable.
Increased risk of sun damage
A weak barrier function is less able to protect against damage caused by the sun’s harmful UV rays which makes skin more susceptible to pigmentation and skin cancer.
A strong dermal barrier strengthens the natural defence against the sun however you must still wear sunscreen every day.
How to protect the skin’s barrier function naturally
The skincare market is saturated with moisturisers and creams designed to protect delicate skin, but the reality is that the ingredients used to create those products are rarely natural and end up causing more harm in the long-term.
Fragrance, emulsifiers, and synthetic activating agents can be known irritants which further weaken the skin’s barrier rather than protect it.
To protect and nourish the ‘stratum corneum’ and restore barrier function naturally, Biologi recommends the following:
Drink lots of water
Water promotes the internal hydration mechanism and keeps cells stronger, brighter and less prone to dryness and flaking.
Even if moisturiser says it’s naturally-derived, the texture and consistency mean it’s made up of synthetic ingredients which block pores. This occlusion then leads to breakouts and inflammation.
If skin cells receive the signs they’re hydrated from the outside, this slows down the natural hydration processes meaning cells no longer hydrate naturally from the inside, and you need more and more moisturiser to avoid dryness.
Always use a water-based serum that doesn’t contain occlusive ingredients and penetrates the deeper layers of the cells to work WITH not AGAINST the natural hydration.
Use active ingredients
Active ingredients are those which have been scientifically proven to change the skin on a cellular level.
Actives don’t require synthetic activating agents to work, and the benefits to the skin are faster, more noticeable and longer lasting.
Avoid the use of synthetics in skincare to avoid irritation and damage to the barrier function so it can protect you as it’s designed to do.
Each serum in the Biologi range is a powerhouse of active ingredients which protect and repair the skin’s barrier function exactly as they do in their botanical source.
Choose from the following:
- Tryptophan – alpha amino acid (Bf serum)
- Vitamin C – carbohydrate (Bk and Bf serum)
- Tartaric acid – fruit acid (Bd serum)
- Quercetin – flavanol (Bd serum)
- Ferulic acid – Hydroxycinnamic acid (Bf serum)
Use a Biologi serum of your choice morning and night to repair, strengthen and nourish the dermal layer so it can look after your body naturally, just as it was designed to do.
